Specification of Letters l atent.

Patented May 31, 1910.

To all whom it may concern:

Be it known that I, EDWARD Conn, a citizen of the United States ofAmerica, and a resident of the city, county, and State of New York, haveinvented certain new and useful Improvements in Kilns, of which thefollowing is a specification.

My invention relates generally to kilns, and has more particularreference to an apparatus in which the bricks are dried, burned andcooled in their passage through the same.

The object of the invention is to facilitate the burning of bricks ingreat quantities in a very short time, and to this end the inventionconsists of the features of construction and combination of parts aswill more fully hereinafter appear.

In the drawings, I have embodied my in vention in a suitable form, butchanges of construction may of course be made within the scope of theclaims.

Fi ure- 1 is a general view showing my compdete improved apparatus,partly in section and broken away. Fig. 2 is a detail view of the meansfor moving the single conveyer into juxtaposition with either of theplurality of tiers of conveyers. Fig. 3 is a detail view of the meansfor driving either of the tiers of conveyers at will. Fig. 4 is a detailview of one of the clutches.

Similar characters of reference indicate corresponding parts in thedifferent views.

1 indicates a kiln'of any suitable construction and having the furnace1.

2 is a drying chamber, and 3 is a cooling chamber. The kiln isinterposed between the two.

Some distance away from the drying chamber there is preferably located abrick molding machine 4 of'any suitable construction for automaticallymolding the bricks.

The kiln is characterized by the fact that I provide a plurality oftiers of rollers 5, 6, 7 and S in the said kiln, and in connection withthis construction I provide a plurality of tiers of conveyers 9, 10, 11and 12 in the drying chamber, and a plurality of tiers of conveyers 13,14, 15 and 16 in the coolin chamber. The rollers in the kiln are preferably polygonal-shaped, the sides of the polygon being of equal lengthandare suitably driven by means of the sprocket chains and wheels 17 and18. These rollers are preferably made of fire clay.

Interposed between the conveyers in the drying and cooling chambers,which are preferably in the form of endless belts or aprons, and therollers in the burning chamber, I provide a plurality of idlers 19 tofacilitate the passage of bricks from the aprons to the rollers.spective shafts 20, 21,22 and 23 of the carrier aprons in the coolingchamber are the pulleys 24, 25, 26 and 27, which receive their motion bymeans of belts connect-in with pulleys 24*, 25,- 26 and 27 on the rivingshaft 28. This driving shaft may be operated by any suitable motor, suchas the one indicated at 29, and is provided with four clutches 30, 31,32 and 33 so that motion may be imparted to either one of the four tiersof conveying means. The parts are preferably so arranged that thecarrier aprons in the drying chamber are driven at one speed, while therolls in the burning chamber and the carrier aprons in the coolingchamber are driven 'at a less speed. This is accomplished by running achain 34 from a sprocket wheel 35 on each of the four shafts 35* overwhich passes the carrier apron of the cooling chamber to a sprocketwheel 36 mounted on the rear-most roller of each of the four tiers. Fromthese rear-most rollers motion is conveyed to all the other rollers inthe same tier by means of the sprocket chains and wheels 17 and 18. Thecarrier aprons in the drying chamber will be geared to the rollers inthe burning chamber by means of the chains 35 passing over the largesprocket 35 on the first roller in each tier of the burning chamber tothe sprocket 35 on the shaft 35 of each carrier apron in, the dryingchamber.

Located adjacent to the carrier aprons in the drying chamber is a sector37 with which engages a gear wheel 38 mounted on the shaft 39, whichmoves up and down in the slot 40, and on which shaft is supported theroller 41 over which the carrier apron 42 passes. The other end of thecarrier apron travels around the roller 43 which is mounted in fixedbearings. This carrier apron moves at a speed higher than that of thecarrier aprons in the drying chamber. Means, as the removable pins 44,are pro- Mounted on the revided whereby the said shaft carrying the gearmay be fixed in alinement with any of the tiers of conveying means inthe drying chamber and moving with this shaft there may be also one ormore idlers 45 mounted on the bracket 46 so that the bricks may passfreely from the single conveyer to any of the tiers of conveyers.

The drying chamber is provided with a chimney 47 and the cooling chamberis provided with a fan 48 so as to more readily establish a circulationof air through the whole apparatus, whereby cool air is drawn in throughthe cooling chamber, thereby aiding in cooling the bricks is thencarried through the burning chamber and out through the chimney 47 inthe drying chamber, thereby aiding in drying the green bricks. Thus thecurrent of air created is in a direction opposite to that of theprogressive motion of the bricks.

Suitable hinged flaps as 49 may be provided both in the cooling anddrying chambers in order to prevent improper circulation of the airthrough the apparatus.

The operation of the device is as follows: The single carrier apron ismoved into alinement with any tier of conveying means in the apparatusand the proper clutch is then thrown in. The bricks will now pass overfrom said single carrier apron to the tier of conveying means with whichit is in aline ment, and will pass through the drying chamber where thegreen bricks are dried. In passing over the idlers 45 and onto theslower moving apron in the drying chamber, the distance between thebricks will be closed up. When one tier of the drying chamber has beenfilled, the single carrier apron will then be moved to another tier ofconveying means, and power thrown off from the first tier of conveyingmeans and applied to another tier of conveying means. This is continueduntil the drying chamber is filled. After this, the single carrier apronis moved back to the tier with which it was first in alinement and poweris again applied. This will cause the bricks already in the first dryingchamber to travel over the idler and onto the tier of rollers into theburning chamber in alinement with the same. Owing to the fact, however,that the rollers in the burning chamber are driven at a less speed, thedistance between the bricks which is caused by shrinkage, will be closedup in passing over the idlers, and the burning chamber will thus becompletely filled. This is continued until one tier of the burningchamber is filled, when the other tiers will successively be broughtinto action and power applied until all the tiers in the burning chamberare filled. Power will now be applied to the tier which was firstfilled,

ceases and the bricks in that tier will be caused to move out ofalinement therewith in the cooling chamber. This will be continued untilall the bricks in all the tiers have been moved into the coolingchamber. In the meanwhile, of course, other bricks coming from themachine will have taken the place of those which have been moved out ofthe drying and burning chambers.
